He told Sky Sports News: "From my personal point of view, I don't think I was well prepared to come back to the Premier League. It is the hardest league, and you need to be fully fit and really ready to compete."

He added: "There is a big feeling of failure. Most of us came to help the team, believing we could have an impact."

Samba said he was unsure whether he would still be Loftus Road next season, adding: "I don't know. I am not the only one who makes these decisions. I have failed to help the team, and I only know that I will be much stronger next season."
